Griginal application filed January 7, 1915, Serial No. 996. Divided and.this application filed April 5, 1916. Serial No. 89,215.

To all whom it may concern:

Be it known that 1, JOHN Ross STEVEN- soN, a subject of the King ofGreat Britain and Ireland and the Isle of Man, and a resident ofGlasgow, Scotland, bleacher, have invented new and useful Improvementsin Stentering or Stretching Devices for Steam gCan Drying-Machines forTextile Fabrics, being a division of my application for U. S. Patent,Serial No. 996, filed Jan. 7, 1915, of which the following is aspecification.

This invention comprises improvements in stentering or stretchingdevices for steam can drying machines for textile fabrics such as thatshown and described in my English Patent #8553, A. D. 1912.

The steam can drying machine to which the improvements of this inventionare applicable consists of a series of revolving heated cans orcylinders'arranged parallel with each other with their axes horizontal.Above the cans and intermediate of same a series of grooved wheels arearranged and fitted with connecting bars or members so that each wheelon the one side forms with the opposite wheel on the other side and theconnecting bars between same a series of drums. The fabric which is heldby stenter ing pins or clips arranged in the form of a chain is passedaround the lower surface of the cans and over the drums above andintermediate of the cans. The pins or clips are attached to blocks orcarriages which are guided in suitably formed and placed rails aroundthe cans and drums, and as this construction is clearly shown in theabove noted patent, it is not illustrated in the drawings.

It is desirable to prevent the chain of clips being in contact with thesurface of the cans in order to keep the cans clean and also to avoidthe frictional action of the clips when passing around the cans, and theobject of this invention is to provide means whereby these ends areattained.

In order that others skilled in the art to which the improvements ofthis invention relate may properly understand same I have hereuntoappended one sheet of explanatory drawings in which Figure 1 is a planview of one end of a steam can, Fig. 2 is an end elevation, the canbeing indicated by a circle, and Fig. 3 is a section of the appliancesshown to a larger scale.

Referring to these drawings In carrying the improvements of thisinvention into effect or practice a ring plate 25 is placed around thesteam can 2 but does not closely fit as its diameter is such as to leavea small clearance space between it and said can. The ring plate 25 isformed with two radial flanges 26 between which the carriages and clips(hereinbefore mentioned) carrying the cloth travel. l/Vhen the machineis working the pressure of the chain of clips keeps the ring 25 in closecontact with part of the surface of the can. lVhen it is desired toadjust the distance between the chains, these are slackened, thusallowing the ring plate 25 to recede from the surface of the can when itcan be easily moved to the required position on the drum by any suitablemeans or by hand.

What I claim and desire to secure by Lettors Patent is 1. Thecombination of the cylinder of a drying machine, with means forpreventing direct engagement of the fabric-carrying chain and saidcylinder, consisting of a ring plate loosely mounted on said cylinder.

2. The combination. of the cylinder of a drying machine, with means forpreventing direct engagement of the fabric-carrying chain and saidcylinder, consisting of a ring plate loosely mounted on said cylinder;and means on said ring plate for guiding the chain.

3. The combination of a drying machine cylinder, with a ring plate forthe reception of a fabric-carrying chain, mounted .on said cylinder andadjustable longitudinally thereof.

4. The combination of a drying machine cylinder; a ring plate mounted onsaid cylinder and adjustable longitudinally there of; with chain guidingflanges on said ring p ate.

5. The combination of the cylinder of a name to this specification in'the presence of drying machine with a ring slidably mounttwo subscribingWitnesses.
